expressions: concat: add typeof support

Previous patches allow to pass concatenations as the mapped-to
data type.

This doesn't work with typeof() because the concat expression has
no support to store the typeof data in the kernel, leading to:

map t2 {
    typeof numgen inc mod 2 : ip daddr . tcp dport

being shown as
     type 0 : ipv4_addr . inet_service

... which can't be parsed back by nft.

This allows the concat expression to store the sub-expressions
in set of nested attributes.
